Technical Overview

The Festo LFR-1-D-5M-MAXI-MPA (Part No. 8002323) is a high-performance, D-series filter pressure regulator. It seamlessly integrates a 5-micron particulate filter and an adjustable pressure control valve into a single, compact Maxi-size frame. Engineered with a robust die-cast zinc housing and a protective metal bowl guard, this unit delivers an impressive standard nominal flow rate of 8,000 l/min. It is ideal for heavy-duty industrial applications requiring high-volume, reliable pneumatic preparation and features an integrated analog MPA pressure gauge, rotary knob with detent, and manual condensate drainage.

Industrial Applications

1. Heavy-Duty Automated Machining Centers

Filtering and regulating the primary shop air supplied to heavy pneumatic actuators, tool changers, and clamps in CNC machining centers.

Problem Solved

Untreated plant air often contains particulates that can jam sensitive pneumatic valves. The 5 µm filtration ensures system longevity, while the massive 8,000 l/min flow rate guarantees that multiple high-volume pneumatic cylinders can fire simultaneously without experiencing performance-degrading pressure drops.

Pneumatic Actuation5 µm FiltrationHigh Nominal Flow (8000 l/min)Pressure Regulation

2. High-Volume Packaging and Palletizing Machinery

Regulating primary pneumatic supply pressure and maintaining air purity for end-of-line packaging systems, including Cartesian gantry robots and pneumatic pick-and-place grippers.

Problem Solved

Inconsistent air pressure can lead to dropped payloads by vacuum and mechanical grippers, while particulate matter can foul proportional control valves. The precise 0.5 to 12 bar regulation range and fine 5 µm filtration protect downstream components, ensuring consistent gripping force and cycle times.

3. Industrial Spray Coating Air Supply

Delivering an exceptionally clean and stable compressed air supply to industrial paint atomizers and automated coating booths.

Problem Solved

Surface finish quality is highly sensitive to air purity and pressure fluctuations. Particulates over 5 microns cause visible defects, and high pressure hysteresis leads to uneven coating thickness. The MAXI filter regulator isolates these contaminants and maintains strict stability with a low 0.4 bar maximum hysteresis.
